STOVE.

Specification of Letters Patent.

Patented June 8, 1920.

Application filed December 7, 1918. Serial No. 265,791.

To all whom it may concern:

Be it known that I, PHILIP P. MELANSON, a subject of the King ofEngland, residing at Moncton, in the Province of New Brunswick andDominion of Canada, have invented a new and useful Stove, of which thefollowing is a specification.

The stove upon which this application is based, includes novel meanswhereby cold air may be drawn in from below and heated, novel meansbeing provided whereby the products of combustion may traverse the stoveand escape, the construction being such that the air will be heated to ahigh degree, with a very small expenditure of iuel.

It is within the province of the disclosure, further, to improvegenerally and to enhance the utility of devices of that sort to whichthe present invention appertains.

WVithin the scope of what is claimed, I do not bind myself to thespecific form shown in the drawings, since, within the field of hisskill, a mechanic may work; changes without departing from the spirit ofthe invention.

In the drawings :*Figure 1 is a vertical section showing a stoveembodying the invention. Fig. 2 is a side elevation wherein parts appearin section; Fig. 3 is a top plan; Fig. 4 is a cross section on the lineH of Fig. 1.

In carrying out the invention there is provided a base 1 supported onlegs 2, or otherwise. The bottom of the base 1 has a depending nipple 3connected to a pipe 4 controlled by a damper 5. There are openings 6 inthe bottom of the base 1, and the side wall of the base may be suppliedwith openings 7 controlled by dampers 8 which may be pivoted at 9 to theside wall of the base. The base 1 includes a top 10.

A central or main flue 11 is carried by the top 10 and communicates withthe base 1. Side or auxiliary flues 12 are connected with the top 10 andcommunicate with the base 1. The numeral 14: denotes an outer drum, andthe numeral 15 marks an inner drum, the bottoms and the side walls ofthe drums being spaced to form a chamber 17 closed at its top by aflange 16 on the inner drum 15, the flange extending across the upperedge of the outer drum 14. The outer drum 14 is provided with a collar18 carrying one end of a pipe 20. The auxiliary fiues 12 pass throughthe bottom of the outer drum l4: and are assembled with the bottom ofthe inner drum 15, the flues thus communicating with the base 1 and withthe interior of the inner drum 15. The upper end of the main flue 11 isassembled with the bottom of the outer drum 14, and the fine 11,therefore, communicates with the base 1 and the chamber 17 which existsbetween the drums l4 and 15. The heating means may be of any sort, but,if desired, it may be in the form of a burner 21 located in the mainflue l1 and carried by a pipe 22 extended laterally through the flue 11.The openings 6 in the bottom of the base 1 are located directly belowthe auxiliary flues 12.

In practical operation, the products of combustion proceeding from theburner 21 pass upwardly through the flue 11, into the chamber 17, andout through the pipe 20, the inner drum 15 being heated in this way, andthe outer drum 14 being heated also, the drum 14 serving to heat the airin the room, about the said drum. When the products of combustion moveupwardly through the flue 11, cold air is drawn into the base 1, throughthe openings 6, through the pipe 4 if the damper 5 is open, or throughthe openings 7 if the dampers 8 are open. In this way, a regulatedsupply of air is provided, the pipe 4 forming a means whereby air may bedrawn from a point outside of the building, if desired. The air passesupwardly through the fiues 12 into the drum 15 and there is heated, theheated air passing out of the top of the drum. The construction of thedevice is such that a maximum amount of air may be heated with theexpenditure of a minimum amount of fuel.

I claim A stove comprising a base including a top, a bottom and a sidewall; inner and outer drums having their bottoms and their side wallsspaced to define a chamber having an outlet for the products ofcombustion; a central main flue connected to the top of the base and tothe bottom of the outer drum and establishing communication between theinterior of the base and the chamber; auxiliary flues disposed about themain flue, the auxiliary flues passing through the bottom of the outerdrum and being connected to the bottom of the inner drum and to the topof the base, the auxiliary fiues establishing communication between thebase and the interior of the inner drum, the bot- 5 tom of the basehaving openings alined with the auxiliary flues, the bottom of the basehaving an aperture alined with the main flue, and there being anaperture in the side wall of the base; and dampers controlling therespective apertures. 10

In testimony that I claim the foregoing as my own, I have hereuntoafiixed my signature.

PHILIP P. MELANSON.
